Hi Christina, and welcome to planDisney!
It sounds like you will have a bunch of loved ones in tow to share this dining experience with! Talk about memories!
‘Ohana at Disney’s Polynesian Village Resort is a wonderful dining experience, especially if you plan to dine during breakfast at the Best Friends Breakfast featuring Lilo & Stitch. Yes, as long as availability exists, you can reserve dining for your group size via the
My Disney Experience mobile app. If availability isn’t available for your timeframe, keep checking, as an opening could become available anytime before your arrival. Also, on the day you plan to dine there, you can “Join Walk-Up List,” and there is a possibility you can get in the same day.
Please let us know if you have additional questions.
Have a magical meal!
Raquel
